北京市实施测土配方施肥项目已经实现了从试点到大面积推广和全覆盖,对提高京郊农业产量,增加农民收入和推动北京市都市型农业发展起到了巨大作用。北京市实施测土配方施肥项目以来,各种技术性问题逐渐被攻克,正在经历由技术体系研究和推广向培育农化服务体系的新阶段。从宏观来讲,测土配方施肥分为三大体系,即技术体系、农化服务体系和肥料产业体系。在这3个体系中,技术体系是基础,农化服务体系是保障,肥料产业体系是目标。开
The implementation of the soil testing and formula fertilization project in Beijing has achieved a great effect from pilot projects to large-area popularization and full coverage, which have played an important role in raising agricultural output in the suburbs of Beijing, increasing farmers’ income and promoting urban agriculture in Beijing. Since the implementation of the soil testing and fertilizer project in Beijing, various technical problems have gradually been overcome and are undergoing a new phase of research and extension from the technical system to the cultivation of agricultural service system. From a macro perspective, soil testing and fertilizer formula is divided into three major systems, namely, technical system, agricultural service system and fertilizer industry system. Among these three systems, the technical system is the foundation, the agro-chemical service system is the guarantee, and the fertilizer industrial system is the target. open
